Hmm, from kdelibs/kstyles/keramik/CMakeLists.txt:

set(genembed_SRCS genembed.cpp )

kde4_automoc(${genembed_SRCS})

# basically an add_executable:
# with EXECUTABLE_OUTPUT_PUT = ${CMAKE_BINARY_DIR}/bin
kde4_add_executable(genembed ${genembed_SRCS})

target_link_libraries(genembed  ${QT_AND_KDECORE_LIBS} kdefx )

# generate some file...
file(GLOB keramikPics "${CMAKE_CURRENT_SOURCE_DIR}/pics/*.png")
file(WRITE ${CMAKE_CURRENT_BINARY_DIR}/keramikPics.txt "" )
foreach(pics ${keramikPics})
   file(APPEND  ${CMAKE_CURRENT_BINARY_DIR}/keramikPics.txt "${pics}\n" )
endforeach(pics ${keramikPics})

get_target_property(GENEMBED_EXECUTABLE genembed LOCATION)

# and now the command for generating keramikrc.h
# with a DEPENDS to genembed 
add_custom_command(OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/keramikrc.h
  COMMAND ${GENEMBED_EXECUTABLE}
  ARGS --file ${CMAKE_CURRENT_BINARY_DIR}/keramikPics.txt > 
${CMAKE_CURRENT_BINARY_DIR}/pixmaps.keramik
  DEPENDS genembed ${keramikPics}
)


Shouldn't this be enough ?
I'll have a look at the generated makefiles.

Bye
Alex
